摘要

In land ecosystems, soil carbonates are a buffer reservoir, which is able to release CO_2 into the atmosphere or accumulate it in the soil profile depending on the environmental state and, thus, to influence the temperature of the ground-level air layer on the Earth [1, 2]. As for the CO_2 regime, the dynamics of carbonates is determined by the fact that in its solution in water every molecule of the calcite carbonate binding the CO_2 molecule transforms into bicarbonate form and, then with CaCO_3 crystallization, the CO_2 moves into the atmosphere, according to the reversible equilibrium.
